Directions Located at the corner of 11th St and N. Union St. Easiest access is by I-95. Take the Delaware Ave. exit and continue west on Pennsylvania Ave (Rte 52) until you reach the railroad bridge (just after Union Park Pontiac). Just before the bridge, turn left onto Union Street. Our office is on the corner across from PNC Bank. Our sign (Wilmington MRI Center) is on the brown glass windows of the building.
